Abstract |
|
For frequencies above 30 ghz, increasing skin depth losses in metal requires that low loss structures be made without the use of metallic materials. Hence, the importance of pure dielectrics waveguides for carrying large bandwidth signals is established. The only unexploited spectral region, Terahertz band, is now being actively explored. Moreover, metallic waveguides or antennas are dangerous when the application involves ionized gas i.e. Plasma or when there is a risk that the antenna or waveguide can be exposed to plasma. Dielectric waveguides might be the only viable solution. Here, an analytical theory has been developed for finding out the modal characteristics of a solid dielectric waveguide in guided and leaky modes. |
